Get lost among diggers, perhaps, with setter's upper garments half destroyed (5)
I believe the answer is:
imshi
'get lost among diggers' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'with setter's upper garments half destroyed' is the wordplay.
'with' means one lot of letters go next to another.
'setter's' becomes 'I'm' (referring to the crossword setter).
'upper garments' becomes 'shirts' (I've seen this before).
'half destroyed' means to take half the letters.
'shirts' with half the letters taken is 'shi'.
'im'+'shi' is 'IMSHI'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for imshi that I've seen before include "leave" , "Go away" , "Depart for Arabia" .)
